EmailRep vs dead-drop: common questions

Which is more reliable, EmailRep or dead-drop?

Only dead-drop is on our probe schedule so far (—% uptime over 90 days). The other is catalogued but not yet live-checked, so we can't compare measured reliability head-to-head — check the uncovered API's own status page for now.

Do EmailRep and dead-drop need an API key?

Neither needs a paid key — EmailRep is callable with no signup, and dead-drop is callable with no signup. Both are quick to prototype with; rate limits still apply.

Can I call EmailRep and dead-drop from the browser?

Only dead-drop is browser-friendly — it returns CORS headers over HTTPS. EmailRep needs a server-side call or proxy, so factor that into which one fits a front-end project.

Are EmailRep and dead-drop free for commercial use?

EmailRep has unclear commercial terms, and dead-drop has unclear commercial terms. We track service terms and the data license as separate fields — see the Commercial use and Data license rows above, and confirm both before shipping either in a paid product.
